HI I have a voltage problem I just bought a 2002 Tahoe I have had it for about 3 weeks know and last week I went out to start it and it was dead so I jumped it off and took it to the shop to get a new battery and everything was fine but about 3 nights ago I notice the lights are pulsating all of them and when you turn everything on you can see the voltage gauge in the truck pulsating too kow when you start turning things off it stops so I thought the alterantor was going out so I took it to the shop and they said it checked out fine! so know I don't know what to do they said the called the chevy dealer and they said it is common in those years and sometime replacing the alernator will fix it and sometimes it won't! but it didn't do it until I got this new battery and I didn't check the old one to see what amp rating it was this new one is ca 800 and cca 650 the shop said it is suppose to be like 1000 and 800 but that it still shouldn't be causing the problem so I don't kow where to go from here any help would be great thanks in advance!
